It's available in four colours, and the discount makes it cheaper than most other 3D pens Amazon has recommended to me! I think it's worth a shot, I've been looking for one of these at a decent price and there's a warranty.

There are a few special offers on filaments associated with this item, so that might be worth looking into, under "Promotion Available"
